Climber Will Gladd heads to the island of Labrador off the east coast of Canada, finds himself a little ‘berg, and scrambles the fairly short way to the top. The 38-year-old tells National Geographic, “Soon after I jumped off this brittle, 10,000-year-old berg, a dump truck-size block broke off right where I’d been perched! We learned that mountain boys may well be out of their depths in the North Atlantic.”

Is this genius or incredibly dumb? You decide.
